CHARLES KOEGEL, OF HOLYOKE, MASSACHUSETTS.

SLITTING AND WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 668,754, dated February26, 1901. Application filed November 11, 1897- Serial No. 658,120. (Nomodel.)

T0 at whom, it may concern.-

Be it known that I, CHARLES KOEGEL, a citizen of the United States ofAmerica, residing in Holyoke, in the county of Hampden and State ofMassachusetts,'have invented new and useful Improvements in Winding,Compressing, and SlittingMachines, of which the following is aspecification, reference being had to the accompanying drawings andlet"- ters and figures of reference marked thereon.

The object of my invention is to produce a machine by which paper orother suitable material may be closely wound and formed into athoroughly-compact mass and with which the material may be cut duringthe process of rolling and compacting, this producing, if desired, aseries of rolls of uniform size and formed with smooth and accuratesides and very compact.

I accomplish the objects of my invention by the construction hereinshown.

In the accompanying drawings, in which like letters and figures ofreference indicate like parts, Figure 1 is a perspective of my improvedmachine. Fig. 2 is a front elevation. Fig. 3 is a rear elevation. Fig. 4is an end view as seen from the left of Fig. 2. 'Fig. 5 is a sectionalview taken on line X X of Fig. 2 and looking in the direction of theflight of the arrows, the direction of paper being herein indicated byfull lines and arrows. Fig. 6 is a View, on an enlarged scale, of theupper part of my machine, shown partly in section. Fig. 7 is a view, onan enlarged scale, of the brake and shifting device as seen from thefront. Fig. 8 is a side view of the same. Fig. 9 is an enlargedsectional view of the clutch mechanism. Fig. 10 is an enlarged sectionalview of the boxes in which the cutting-knife shaft is journaled. Fig. 11is an enlarged view of the feed tension-roll in the lower portion of themachine. Fig. 12 is an enlarged view of the tension-roll for holding thepaper firmly to the cutting-roll while it is being cut, showing also itsconnections to the machine. Fig. 13 is an enlarged sectional view of acutting-knife and holder. Fig. 14 is an enlarged front view of acutting-knife and holder. Fig. 15 is a side view of the same.

In detail someof the principal parts are lettered and marked as follows:

A indicates the base of the'machine B, uprights; (J, a stud on which theclutch-pulley mechanism is mounted; D, a gear; E and F,supporting-rolls; Gand H, gears mounted on the supporting-roll shafts;I, rotary cutters; J, cutter-supporting rod; K, cutter-roll; L,-clutch-pulley; M, bearings of cutter=supporting rod; 0, lowerguide-roll; Q, shaft on which the feed or supply roll is mounted; S,shaft lever for the feed-roll; T and U, pulleys.

aindicates the shaft adapted to operate the lifting-screws; c, ahand-wheel mounted at one end of said shaft; 01, beveled gears passingthereto over the top of the supporting-roll F and partially over roll E,so that the roll being formed rests upon the two rolls F and E, mountedupon the lifting-screws; f, lifting-screws; g, lifting-nuts; h, a framemounted between the uprights B; 2', pressureroll; j, receiving-roll orroll upon which the material is wound.

The construction and operation of my inachine may be described asfollows:

A suitableframe A is provided, upon which are mounted guide-rolls,cutting-rolls, a pressure-roll, supporting-rolls, &c. The uprights B aremounted upon the top portion of the frame A, and lifting-screwsfaremounted in said uprights.

The roll of paper or other material to be operated upon is mounted andsupported upon the shaft Q, which shaft is suitably mounted in the backportion of the machine, its preferred location being most clearly shownin Figs. 4 and 5. Suitable brake mechanism, hereinafter described,isarranged for restraining the too-free revolution of the roll ofmaterial. The material is carried from the supply-roll downwardly underthe guide-roll 0, located in the lower portion of the machine, and fromthence is carried upwardly over the cutter-roll K, thence under theguide-roll u, and from thence is wound upon the receivingrollj, thecutting operation being performed while the material is passing over thecutterroll K. The supporting-rolls E and F are preferably formed ofwood, and the roll E has a diameter slightly in excess of the roll F, sothat while the number of revolutions per minute' is the same as that ofthe roll F its periphery travels faster, thus stretching and tightlywinding the paper upon the receivingroll.

The pressure-roll 7; is mounted in a vertically-moving frame It, (shownmost clearly in Fig. 6,) which frame is so constructed as to applypressure upon the receiving-roll j to the desired extent, which pressuremay be regulated by the application of weights, as o, mounted upon thecross-bar n of this frame.

The pressure-roll 2' is mounted with its ends projecting through slotsin the movable frame 7L and is free to be independently moved upwardlyand away from the receiving-roll by the increasing size of the roll ofmaterial being formed.

The guide-r0110, (see Fig. 11,) located in the lower portion of themachine, is provided with bearings having stems p, which stems aremounted in supports q, and coil-springs r are mounted upon the endportions of the stems, so that a cushioning effect is produced, and if,as frequently occurs in a web of paper or other material, one side hasbeen stretched more than the other or the web is otherwise irregularthis inequality will be compensated for by the yielding guide-roll 0,thus avoiding the rupture of the material which might result were thisguide-roll mounted in fixed or unyielding supports, and at the same timea substantially uniform tension is maintained upon the material whetherit be uniform or not. The guide-roll u, (see Fig. 12) is also yieldinglymounted. The bearings 20 for the guide-roll u are provided with stems21, which enter sockets 22, the sockets being pivotally mounted uponlugs 23, which project from the face of the uprights B. The arrangementof the guide-roll it between the cutter-roll K and the supporting-roll Fserves to maintain the paper after it has been cut in a fiat and uniformposition, holding it taut and snugly down upon the supporting-roll untilit reaches the roll upon which it is wound. In the cutting of paper intovery narrow pieces this is found quite necessary, as the tendency attimes is for some of the narrow strips of paper to twist or curl, andthus become diverged slightly from a direct line, thus tending to causeit to he wound in a somewhat-irregular manner, causing the narrow rollof paper afterward to present an uneven appearance wherever a strip ofpaper is wound thereon a trifling distance out of a direct line.

In order to maintain the material in proper alinement as it is woundfrom the roll, the supply-shaft Q is mounted so that it may be adjustedlongitudinally and a lever S engages therewith, whereby the shaft may bemoved to the desired position.

In order to prevent the too-free revolution of the supply-shaft, Iprovide a brake mechanism consisting of a grooved pulley 3,mounted uponthe supply-shaft, and a strap at passes around the brake-pulley 3, oneend of which strap is fixed to an adjusting-screw '7, so that thefreedom with which the supply-shaft revolves may be controlled byincreasing or decreasing the friction upon the brake-pulley by means ofthe adjusting mechanism.

A most convenient means for engagement between the shaft and the leverfor moving it longitudinally is, in my judgment, that illustrated inFigs. 7 and 8, in which I show a supporting-stud 30 mounted upon thelever S, and upon said stud the strap supporting frame 50 is secured, sothat by this construction I utilize the brake mechanism as a means ofconnection between the lever and the shaft. While this means ofconnection may seem to be somewhat flexible and difficult to operatewhile the machine is at rest, it will readily be seen that while thefeed-roll shaft is revolving a slight pressure or strain, tending tocarry the shaft in either direction, will operate to move it in thatdirection, and the lever employed in moving the shaft is only put inoperation ordinarily while the feed-roll shaft is revolving. If desired,the brake-strap-supporting piece 50 may be made to project into thegroove of the pulley 3, and thus furnish a more positive means of movingthe feedroll shaft longitudinally when required to bring the paper inproper alinement.

The rotary cutters I are mounted upon spring-supports 12, which in turnare mounted upon adjustable supporting-collars l3, and these collars areadjustably mounted upon the cutter-rod J, and a spring X is arrangedwhichcontinually forces the rod J in one direction, while for thepurpose of carrying this rod in the opposite direction a screw 24,having a hand-wheel w, is provided, the screw being arranged to projectthrough the bearing and bear against the end of the rod J. Thisarrangement of parts enables me to properly adjust the rodlongitudinally and insures a continual shearing contact between thecutting edges and avoids danger of breaking or injuring the cutters andalso enables me to move all of the cutters in unison, so as to bring thecutting edges together or to separate them simultaneously. The spring isarranged to force the rod J in a direction to carry the cutters againstthe cutting-disks of roll K, thus maintaining the cutting edges incontact by a spring-pressure. When it is desired to separate all thecutting edges at once, the hand-wheel at the end of the shaft oppositethe spring is turned, thus revolving the threaded rod to which it isattached and forcing the cutter-supporting rod J against the spring andmoving the cutters laterally away from the cutting-disks of the roll K.

The cutter-roll K is constructed by the employment of hardened-steeldisks mounted upon ashaft, these disks or rings being preferably held infixed position against movement longitudinally on the shaft byintervening collars or rings.

By the arrangement and construction herein shown it will be seen thateach cutter may be readily adjusted so that the sharpened cutting edgewill lie against the face of the IIO hardened-steel disk or ring, thisindividual adjustment being accomplished by adjusting the split ringorcollar 13 upon the supporting-rod J, and each spring-support 12 mountedupon its split ring. A support 13 will at all times tend to force itsindividual cutter in the desired direction, while all of the cuttersmay, as before stated, be simultaneously adjusted longitudinally bymoving the rod J, and the cutters may. all be moved toward or from therollK by rotating the supportingrod J, moving the attached supports 12,mounted on the collars or split rings 13 and carrying the cutters to thedesired position.

The cutters I have large central openings and are mounted uponball-bearings, the balls 25 traversing the periphery of a central part25 and collars 26 and 27 being arranged upon each side, this preventingthe escape of the balls and at the same time insnringa free andfrictionless revolution of the cutting-blade upon its support.

It will readily be seen that while it is more convenient to mount a ringor part 25 upon the supporting-stud than to provide a stud having ahardened surface the same result will be accomplished if the ballstraverse the stud itself instead of the ring 25, mounted upon the stud,and I do not limit myself to the arrangement of a ring mounted upon thestud, although I deem this method of construction most convenient, andin this connection I deem the stud with a straight body and astud withan enlargement thereon either formed integral therewith or independentlyand mounted thereon equivalents.

The lifting-screwsfare mounted, as before stated, in the uprights B, andthe nuts g are threaded to engage the thread on the screws f, and thesenuts are provided with offsets or lugs 28, which project through theslotted openings in the inner faces of the uprights B, so as to restunder the ends of the pressure-roll 11. When, therefore, these screwsare turned in a direction to carry the nuts 9 downwardly a sufficientdistance, the pressure-roll 1 will rest against the receiving-roll joragainst the material wound thereon, while if these screws are turned inthe opposite direction the nuts 9 will be carried upwardly, and theirlugs, resting under the ends of the pressure-roll i, will engage theroll at the ends and carry it upwardly also, and if it be desired toremove the weight from the receiving roll j then pins may be insertedthrough the opening 6 in the frame It, thus preventing'the furtherupward movement of the pressure-roll i in the frame h, and the furtherupward movement of the nuts 9 will result in moving the frame andpressure-roll together from the receiving-roll, thus relieving thereceiving-rollj from pressure and also moving the frame out of the way,so that the receiving-roll, with the material wound thereon, may beremoved from the machine.

For purposes of illustration I have chosen to use the mechanism composedof a screw and nut regulated by bevel-gears for vertically adjusting thepressure-roll and frame h. I do not intend, however, to confine myselfto this particular mechanism, as it will readily be seen that the sameresult may be attained by the employment of other mechanical appliancesarranged for lifting the parts.

When the Winding operation is begun, the paper or other material iswrapped around the receiving-roll j, the frame it and pressureroll 't'lowered to place, and the lifting-screws turned slightly,so as to allowthe pressure-roll to bear and rest upon the material wound upon thereceiving-roll,and if great compactness is desired then weights 0 may beplaced on .the cross-beam n of the frame h, thus bearing thereceiving-rolljdownwardly upon the supportingrolls E and F with greatforce, and the material is further subjected to pressure as it passesbelow the pressure-roll 2'.

To insure uniformity in the revolution of the lifting-screws and torender them easy to manipulate,beveled gears e are mounted upon theirupper ends, and like gears meshing therewith are mounted upon thelifting-shaft 0t, and a hand-wheel is provided at one end of the shafta, so that the same may be conveniently revolved. Thus it will be seenthat a revolution of the shaft a will cause the gears e to revolve byreason of the gearsd meshing therewith, and thus the lifting-screws fwill be revolved in the desired direction.

Motion is imparted to the various parts of the machine by the employmentof gear D being mounted upon the part 10 of the clutch and thesetogether being mounted upon a stud O, suitably secured to the frame. Aclutchpulley is mounted also on thestud O and provided with engagingfriction-faces to engage the partlO. A hand-wheel W is mounted upon thethreaded end of the stud C, and upon its being turned in one directionthe clutch-pulley is moved forwardly and caused to engage with theopposite friction-surface, while if itis turned in the oppositedirection the clutch-pulley is free to revolve independently.

To avoid friction between the fixed and moving parts, I provideball-bearings, as shown at w in Fig. 9.

The gear H is mounted upon the end of the shaft on which the supportingroll F is mounted, and its teeth mesh with the teeth of the gear D,whilea like gear mounted upon the shaft upon which the roll E is mountedmeshes with the same gear.

By the employment of the clutch mechanism described the machine may bestarted or stopped instantly or gradually by properly manipulating thehand-wheel W, while the portion of cl utch-pulley on which thedrivingbelt is mounted continues to revolve at a given speed.

It will of course be seen that this machine may be employed for closelywinding paper or other material without cutting or slitting and that thecutting or slitting mechanism IIO may be employed without the employmentof the mechanism for closely rolling or windmg.
